Check your cam card before buying ratio rockers.BUY AT YOUR OWN RISK.Remember, just because the math says it will work, doesn't mean your heads will let it work. Coil bind gap is critical.

Here's the math formula to use to determine if you can run ratio rockers that are 1.25:1 style. A Engle 110 cam has a 430 published lift, so, divide 430 by 1.1, that equals 390, multiply 390 by 1.25, the answer is your new lift of 488.64
